Why we use virial equation of state?
The perfect gas law is an imperfect description of a real gas, we can combine the perfect gas law and the compressibility factors of real gases to develop an equation to describe the isotherms of a real gas. This Equation is known as the Virial Equation of state, which expresses the deviation from ideality in terms of a power series in the density.
The actual behavior of fluids is often described with the virial equation:
PV = RT[1 + (B/V) + (C/(V^2)) + ...] ,
where,
B is the second virial coefficient,
C is called the third virial coefficient, etc.
in which the temperature-dependent constants for each gas are known as the virial coefficients. The second virial coefficient, B, has units of volume (L).
How to Calculate Second Virial Coefficient using Reduced Second Virial Coefficient?
Second Virial Coefficient using Reduced Second Virial Coefficient calculator uses Second Virial Coefficient = (Reduced Second Virial Coefficient*[R]*Critical Temperature)/Critical Pressure to calculate the Second Virial Coefficient, The Second Virial Coefficient using Reduced Second Virial Coefficient formula is defined as the ratio of the product of the reduced second virial coefficient, the universal gas constant and the critical temperature to the critical pressure. Second Virial Coefficient is denoted by B symbol.
